Report: RG3 fractures thumb, Ravens optimistic he'll be ready for Week 1

The Baltimore Ravens might be without their No. 2 quarterback for the rest of the summer.

Robert Griffin III sustained a small fracture in his thumb Saturday night, sources told Jeff Zrebiec of The Athletic. The Ravens are reportedly optimistic that he'll be ready for Week 1.

Griffin suffered the injury after banging his hand off a defender's helmet in practice, according to Zrebiec.

The veteran signal-caller appeared to reference his injury on Twitter:

Rookie Trace McSorley, who was selected in the sixth round, is the only other quarterback on Baltimore's roster.

Griffin barely saw the field in his first season with the Ravens in 2018, tossing six passes in three appearances.
